+### 06/19/2018 0.4.49
+- Bug fix: Data is valid against more than one schema from `oneOf` [#248](https://github.com/Azure/oav/pull/248)
+  The problem occurs when referenced model may also accept `null`. The fix is replacing `oneOf` with `anyOf`.

 ### 05/14/2018 0.4.38
 - Bug fix: `oav extract-xmsexamples` also extracts request headers. [#241](https://github.com/Azure/oav/pull/241)
 - Bug fix: x-ms-parametrized-host is not validated correctly [#240](https://github.com/Azure/oav/issues/240)
